Goldman Sachs holds the strongest implied probability at 83.5% to serve as lead underwriter for OpenAI’s IPO, reflecting its recent lead-left role on the SpaceX offering and primary position alongside Morgan Stanley in OpenAI’s confidential S-1 filing submitted in late May 2026. Traders price this edge based on Goldman’s dominant share of major tech debuts and execution track record, while Morgan Stanley’s 15.5% reflects its comparable bookrunner involvement in both OpenAI and Anthropic preparations but secondary standing in allocation influence. JPMorgan and other banks appear limited to supporting roles in the syndicate. The outcome hinges on official disclosures from OpenAI, with a potential listing window eyed for late 2026 or 2027 amid the company’s $1 trillion valuation target and ongoing SEC review.

If no IPO occurs by December 31, 2027, 11:59 PM ET, or OpenAI completes an initial public offering without a designated lead underwriter, this market will resolve to “Other.”
If multiple banks are identified as lead underwriters, this market will resolve according to the primary lead underwriter. If the hierarchy between them is unclear, this market will resolve once it is conclusively evident which bank is the primary lead underwriter, for example, through the order in which the banks are listed in the underwriting section of OpenAI's final initial public offering prospectus, once released.
The primary resolution source for this market will be official disclosures from OpenAI. A consensus of credible reporting may also be used.
